Abstract: his paper deals with the satellite link budget in 3 different aspects which are: How to determine the coverage in to percentage form by using Pythagoras theorem in addition of some assumptions, second aspect is the required power toward and from the satellite, and last aspect is how to eliminate the earth station performance in percentage form by using Eb/No. The research takes 25 locations in the Sudan, gives for each location the specific code. The overall output the OBO ,IBO ,distance ,OFD,C/N,C/Tu ,C/Tco - ch ,C /Ty , Lu ,Ld all are required in order to achieve the 3 aspects. Also enhancing the performance to the optimum in regardless of coverage location is done by controlling in 3 main parameters, this means, the coverage is not a problem in reaching the optimum performance.

Abstract: The purpose of this paper, is to provide a solution to the issue of dependence for elderly people in the context of an ageing population phenomenon. In rural areas with a low population density, isolation has negative impacts on everyday life. In France, the ageing population raises the fear of a serious increase in the number of persons suffering from disabilities and in need of assistance. In Corsica, population ag e ing is substantially increasing. Given this critical context we are try ing to develop a system of connected objects called SmartAngels to support proximity - based solidarity. It consists of a meshed network of autonomous Zi g Bee microcontrollers, in which various actors can exchange information by means of an accurate interface design. Its main task is to support both proximity - based solidarity and social relat ionship s in rural environments. Moreover, the SmartAngels device grid ensures optimal neighbo u rhood solidarity in case of a serious problem by creating a
